Copper does not naturally corrode in most clays, chalks, loams, sands, and gravels. Certain aggressive soil conditions, however, can cause it to corrode. The basic prerequisite for corrosion is the presence of appreciable amounts of moisture.
Magnesium - Wikipedia
Magnesium is a chemical element with the syol Mg and atomic nuer 12.It is a shiny gray solid which bears a close physical reselance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.
